CAD is caused by a narrowing of coronary arteries, called atherosclerosis. Blood flow becomes more and more restricted as the artery continues to narrow. Most commonly, atherosclerosis results when cholesterol and fat circulating in the bloodstream build up on the artery walls. The triggering event is an injury to the artery\'s inner lining; the injury can be caused by high blood pressure, diabetes, or other causes. The body\'s immune system responds to the injury, causing inflammation. Immune cells called macrophages are activated and try to heal the injury. This process creates a plaque within the artery wall made up of low density lipoprotein (LDL cholesterol), other fats, and macrophages.

Some persons with CAD experience no signs or symptoms something called, \'Silent CAD.\' Silent CAD may remain undiagnosed until the person presents some sign or symptom of heart failure, heart attack, or an arrhythmia. A common symptom of CAD is angina, which is a discomfort or chest pain a person experiences when their heart muscle is not receiving enough oxygen-rich blood. Angina might feel like a squeezing pain or pressure in the chest, jaw, neck, shoulders, arms, or back. The pain tends to worsen with activity, decreasing or disappearing when the person rests. Emotional stress can also trigger angina. It is important to contact a health care provider if you experience any of the following symptoms that are suggestive of angina: * A Fainting spell * Palpitations or dizziness * Shortness of breath after exertion * Pain in the upper part of your abdomen * Unexplained nausea, vomiting, or sweating * Jaw pain that is unexplained by another cause * Shoulder or arm pain inv ...more

The most common symptom of coronary artery disease is angina (also called angina pectoris). Angina is often referred to as chest pain. It is also described as chest discomfort, heaviness, tightness, pressure, aching, burning, numbness, fullness, or squeezing. It can be mistaken for indigestion or heartburn. Angina is usually felt in the chest, but may also be felt in the left shoulder, arms, neck, back or jaw.
